ABSTRACT:
One quarter wavelength monopoles on the top and bottom centerline of the aircraft fuselage provide hemispherical coverage for an airborne transceiver thereby reducing shadowing during maneuver. A solid state pair of PIN diodes capable of transmitting and receiving V.H.F. A.M. band energy are utilized in an antenna lobing switch circuit for alternating between antennas at a switching rate of 25 KHz.
